RUBBER HEEL.

Specification of Letters Patent.

Patented Dec. 24, 1912.

Application filed August 17, 1912. Serial No. 715,644.

in rubber heels for shoes'a-nd boot-s, and especially with reference tomeans for detachably securing a rubber or other like heel in place, soas to admit of the ready removal and renewal or repairing of the heelwhen thesame becomes'worn, the invention consisting in the construction,combination and arrangement of devices hereinafter de-.

scribed and claimed.

In the accompanying drawings: Figure l is an inverted plan of myimproved heel attaching devices; Fig. 2 is a vertical longitudinalcentral'sectional view of a rubber heel provided with my improvedattaching devices; Fig. 3 is a similar View on the plane indicated bythe line a'--a of Fig. 1; Fig. 4 is a detail vertical sectional view onthe plane indicated by the line bb of Fig. 1; Fig. 5 is a detailhorizontal sectional view on the plane indicated by the line cc of Fig.2; and Fig. 6 is a detail vertical transverse sectional view on theplane indicated by the line (l-d of Fig. 1.

In the embodiment of my invention I providea heel plate 1 which is madeof'suitable sheet or plate metal, conforms to the shape of the heel of ashoe or boot and is formed at its sides with depending flanges 2 and atits rear with an extension or arm 3 which .has a depending flange 4,said flange being.

provided with'a lock opening 5. Nearthe front corners of the heel plateare struck up effects 6 which are substantially semi-circular in formwith their curved sides pre .sented to the front edge of the heel plateand openings 7'are formed at the straight rear sides of said ofi'sets.These offsets form keepers, as will presently appear.

In connection with the heel late 1 I also provide a core plate 8 whichisv of a size and shape adapting it to fit on the lower side of theattaching plate 1 and to bear between the flanges 2, 4 ofsa-id'attaching plate. This core plate is provided near its frontcorners with forwardly extending tongues 9 which areadapted to enter theopenings 7 to engage the keepers or otlsets 6 and is also formed at itsfront side with an offset, bent anchoring arm 10. At the rear corners ofthe said core plate are similar anchoring arms 11. An arm 12, whichextends rearwardly, is formed between the anchoring arms 11, and thesides thereof are bent to form clamping fingers 13. The anchoring arm 10has an opening 14 through which extends a locking bolt 15. The saidlocking bolt operates in a housing 16, the rear end of which is securedto the under side of the core plate by the arms 13. The front end of thehousing is formed with an offset portion 17, the front end of whichprojects through the opening 14 in the; anchoring arm 10. The bolt 15 isformed with a stop 13 which operates in the said ofi'set portion 17 ofthe housing, the rear end of the said bolt being adapted to be engagedwith the opening 5 of the flange 4, so as to lock the rear end of thecore plate to the flange 4 after the tongues 9 have been'engaged withthe keepers or oilsets 6. Hence, as will be understood, the core platemay be readily attached to or detached from the attaching plate. Tosecure the bolt in'locking position I provide a substantially U-shapedspring 19 which is arranged between the anchoring arm 10 and the stopflange 18 of the bolt and lies between the bolt and the offset por tion'17 of the housing 16. This spring and also the said offset portion ofthe housing 16 are covered by a housing 20 which bears on the core'plate at a" point just in rear of the anchoring arm 10 and has aforwardly extending attaching arm 21 which is bent arm. a

, The body 22 of the heel, which is nlade of rubber or other suitablesubstance, is molded on the core plate so that the anchoringnrms aroundthe front edge of said anchoring of the core plate are embeddedin thesubstance of the saidrubber heel, as" shown, and hence the core plate ispermanently con- ;nected to the heel and serves't'o secure the latter inplace. The. h'ousin 20 prevents any of the material of which t e rubberheel is formed from'ooining in contact with the spring 19 and.interfering with the action thereof. a

It will be understood that in order to de- 'tach the heel it is onlynecessary to first withdraw the bolt from the opening 5 of the flange 4and to then disengage, the

tongues 9 from the keeper offsets 6. "When:

ever the rubber heel becomes worn it can be melted from the core plateand a new one formed on the latter as will be understood. The attachingplate 1- is here shown as pro vided with openings 23 through whichscrews or other like devices may pass in order to secure the attachingplate to the heel of the boot or shoe on which the device isto be worn.

Having thus described my invention I claim:

1.: In a heel, the combination of an attaching plate havingkeepers witha core plate having anchoring means to be embedded in the substance of aheel, the said core plate being further providedwith tongues to engagecertain of the keepers of the attachingplate, a movable bolt carried bythe core plate and adapted to be engaged with the other-keeper of theattaching plat-e, aspring to hold the bolt in normal locking position,and a housing to cover said spring and the contiguous portions of thebolt for the purpose-set forth. v

. 2. "Ina heel, the combination of an vattaching plate-havingkeeperswith a core plate having anchoring arms to be embedded in'thesubstance of a heel,,:the said core plate being further provided withtongues totengage certain of the keepers oft-he attaching plate, alongitudinally movable ,bolt

carried by the :core plate and adapted, to be engaged withthe other.keeper of the attaching plate and means for holding the bolt inno-rmallocking position.

3.-.In a heel the. combination of an attaching-plate having keepers witha core plate .a forwardly extending having anchoring arms to be embeddedin the substance of a heel, saidcore plate being further provided withtongues to engage certain of the keepers of the attaching plate, alongitudinally movable bolt carried by the core plate and adapted to beengaged with the other keeper of the attaching plate, a housing for saidlongitudinal movable bolt, said housing being oflset on one end, and aspring dispose-din the offset portion of said housing to normally holdthe bolt in locking position.

4:. Ina heel the combination of an attaching plate having keepers with acore plate having anchoring arms to be embedded in the substance of aheel, said core plate being further provided with tongues to engagecertain of the keepers of theattaching plate, a longitudinally movablebolt carried byfithe core plate and adapted to be'e'ngaged with one ofthe keepers of the attaching plate, a

housing for said longitudinally movable bolt, said housing being'otfseton one end, a spring disposed in the offset portion of said housing tonormally'hold the bolt in locking position, and a second housing adaptedto cover the offset portion of the first mentioned housing, said secondhousing having arm which isadapted to be bentaroundone of said anchoringarms, as and for the purpose set forth.

In testimony whereof I hereunto atfix my signaturein the presence'ot twowitnesses.
